This invention relates to pipe-supporting arrangements particularly for use on vehicles,- and has for its primary object the provision of such an arrangement wherein expansion and contraction of the pipe is readily permitted without adversely affecting the pipe and in which the pipe is fully free to move without resistance but in fixed, spaced relation to a supporting member.

Other objects of the invention are the provision of a pipe-supporting arrangement afford- I ing adjustability with respect to the height of the pipe. and/or number of pipes supported; individual and independently movable supports for each pipe when a plurality of pipes are used; pivotal supporting brackets with pivotal pipe clamps; and a pipe-supporting arrangement adapted to carry both heating and water supply pipes entirely independently of each other.

The foregoing and other objects are attained by the mechanismillustrated in the accompanying drawings, in which- Fig. 1 is a view of a single heating pipe installation in a room supported in accordance with this invention and havingwater pipes also supported therewith.

Fig. 2 is a cross-sectional view taken on the line 2-2 of Fig. 1 showing th supporting bracket arrangement for the heating and water pipes;

Fig. 3 is an exploded perspective view of the supporting bracket showing the parts in disassembled relation; and

Fig. 4 is'a cross-sectional view similar to Fig. 2 but illustrating an installation supporting a plurality of heating pipes.

In the drawings, ID represents a railway car having a side frame including posts H and an underframe l2 supporting a floor l3 The car illustrated happens to be a room car, therefore the invention is disclosed as applied to a single room and consists of a single finned-pipe heating radiator i4 anchored, at one end, to side wall plate 9 secured to the posts 1 i and carried, at the opposite end, by the supporting bracket of this invention. The radiator l4, at one end, is connected to a source of heating medium (not shown) by means of a feed pipe l5 and a return pipe l6, and, since it is anchoredto the wall 9 at this same end by a bolt ll taking the inlet and return fitting l 8, movement due to expansion and contraction, as the heat is turned on and off, will occur at the opposite end of the radiator where it is carried in supporting bracket 2%]. The wall plate 9, where the bolt ll enters, is reinforced on the back side by a tapping plate l9 into which the bolt is threaded to provid a rigid anchor.

Fig. 2. i

To permit expansion and contraction of the pipe 14 without restraint, the bracket providesa doubly pivoted-joint accommodating all movement of the pipe while positively supporting it in spaced relation to the wall, as best'shown in The bracket 20 iscomprised of a number of parts, best shown in Fig. 3, and of which the support bar 2! forms the basic supporting member. The bar 2|, at its lower end, is welded into a supporting and attaching bracket 22 which forms a means of securing the bar to the side wall by bolts 23 threaded into backing plate 24 and also actsas a support, as will hereinafter appear. At its upper end, thebar 2! is secured to a seat support angle 25 attached to the side wall-and is tapped to receive a screw 26 extending through the horizontal flange of the angle which forms the connection therebetween. A swinging bracket 21 is pivotally associated with the bar 2| by means of bearing 28 encircling the bar and supported on spacing tube 29, also encircling the bar, and extends outwardly from the bar 2| to provide a bearing 30 for a pipe clamp 3i pivotally associated with the bearing 30 by means of a bolt 32 extending through the bearing and having a shoulder 33 against which the clamp is drawn by a nut 34. By providing the shoulder 33 on the bolt, the nut 34 is prevented from causing a binding action between the clamp 3i and the head on the bolt as the nut is drawn tight, so that a freely pivoting relationship between the 7 bolt and bracket 21 is assured, whereby a doubly pivoted joint between the pipe clamp and supporting bar is afiorded by the pivotal bearin s 23 and 30. A spacer 29 spaces the bearing 28 from the lower side of the horizontal flange of the angle member 25.

The pipe clamp 3| comprises a saddle 35 supporting the pipe I4 andseated about the shank of bolt 32 against the shoulder 33, and a clamp 3'5 disposed about the bolt in engagement with the pipe l4 and having a flanged end 3"! engaging the saddle 35 edgewise and about which it fulcrums to tightly engage the pipe l4 as the nut 34 is drawn home. The pipe clamp 3| is rigidly clamped against the shoulder 33, and there is no relative movement between the pipel4 and the clamp, nor between the clamp and theboltthe only movement being pivotal movement'of the bolt within the bearing 30, and it will be seen that by the provision of the double pivoted relationship between the pipe I4 and bracket 21 the pipe is free to expand and contract without frico tional restraint of any kind.

Hot and cold water supply pipes 40 and 4|, respectively, may also be carried by the bracket 20 and are equally adapted to ready movement without frictional resistance. A swinging bracket 42 carries both pipes and is supported on the bar 2! by a section 29 of the spacing tube 29. The spacing tube section 29 rests on the supporting bracket 22 and directly underlies pivot bearing 43 of the bracket 42 on which the tube 29 is supported. The swinging bracket 42, like bracket 21, aifords a doubly pivoted joint between the pipes and supporting bar 2|. bracket extends outwardly from the pivoted bearing 43 and is provided at its extremity with a bearing 44 in which pipe clamps 46 .and 41 are pivotally supported by means of double-ended bolt 45. The pipe clamps 46 and 41 are exactly like the pipe clamp 3|, therefore a description of that clamp arrangement is equally applicable to the water pipe clamps which, accordingly, will not specifically be described. The bolt 45 is provided with shoulders 48 against which the pipe clamps are drawn in opposing relation by nuts 49 to provide sufiicient clearance therebetween to accommodate the bearing 44 without frictional resistance, thereby freely to permit expansion and contraction of the pipes without restraint.

A coil spring 50 is disposed about the bar 2! beneath the lower surface of the bearing 28 of bracket 21 and is seated on a washer resting on the upper end of spacing tube 29 and exerts a constant pressure on all of the parts to insure a tight anti-rattle fit of all of the parts between the supporting and attaching bracket 22 and the horizontal flange of the angle member 25, but permits ready pivotal movement of the bracket 21 without the necessity for providing clearances between the various parts for that purpose, and while the spring, as shown, is disposed beneath the bearing 28, it might be otherwise in the assembly and still serve its purpose.

The heating pipe [4 and the water pipes 40 and 4|, with all fittings and supports, are concealed by an ornamental grille 52 which is removable for access to the parts for maintenance and is supported on the'angle '25 and forms a part of the side finish of the car.

While the invention has been described as applied to a single room, it is, of course, equally applicable to systems involving the use of pipes of greater length in which any number of the supporting brackets of this invention might be used to carry the pipe and permit expansion and contraction throughout the length thereof to any degree and without restraint, thereby to prevent buckling or distortion of the pipe. The heating and/or water pipes are adjustable with respect to their height from the floor merely by changing the length of the spacing'members 29, 29 and 29 and, while only one heating pipe has been described as being carried by the supporting bracket 28, a plurality of heating pipes may be supported on the bracket, as shown in Fig. 4, wherein a plurality of swinging brackets I21 are pivoted on the vertical bar l2| and separated by the spring I50 disposed between the respective bracket pivot bearings I28, the lowermost of which is supported on the shorter spacing tube 129 resting on the pivot bearing I43 of waterpipe-supporting bracket I42 as before. Each of the brackets l2! supports a heating pipe H4, as before, and which may be independent of each other, or a continuous pipe loop and of any length requiring any number of pivotal supporting brackets.

The

From the foregoing, it will be seen that there has been provided a pipe-supporting arrangement having pivotal means permitting longitudinal movement of the pipe due to expansion and contraction without binding action of any kind and supporting pipes of dilferent expansion and contraction characteristics and in which the pipes are easily removable and replaceable without disturbing the supporting bracket assembly.
